Upcoming construction proposals for utility-scale photovoltaic plants and discussion of compensation in Nigeria raise the question of appropriate grid code requirements to support system voltage control objectives. The large geographical extent, long lines, and small number of generators in the Nigerian High Voltage System make voltage control a critical issue. This paper evaluates the effect of different...
In Grid-Connected PV system should not be limited injecting the active power into the grid. However, it must be able to absorb or to generate sufficient reactive power for a certain amount of time according to the grid demand and maintain the grid voltage. This paper proposes sliding mode control that controls powers respectively the active and the reactive power for a Three-Phase Grid-Connected PV...
This paper concentrates on the control of power flow in single stage photovoltaic energy conversion system. The conversion structure has a twofold requirement that consists in ensuring that the current injected to both load and grid obeys to the grid connection standards and sets the DC bus voltage similar to the reference voltage given by the MPPT algorithm. The advanced functions that can be added...
This paper presents a new grid-connected strategy for axial field flux-switching permanent magnet (AFFSPM) wind power generator with improved dynamic response and steady-state performance. Non-controllable convertor and grid-connected PWM rectifier are used as the structure of the main circuit. Triple-state direct power control(DPC) strategy is used on grid side to improve the accuracy of power decoupling...
The emergence of large amounts of distributed energy resources (DER) poses new challenges for the active participation of those units in the control of the grid. In this context, a recent development is the microgrid, which presents a coordinated approach for integrating the DER in the electrical grid. Microgrids are able to operate either connected to the distribution grid or in islanded mode. In...
In terms of optimal Microgrid (MG) control, the output power of a non-dispatchable Distributed Generation (DG) as a Photovoltaic (PV) system need to be controlled based on the optimal operating condition of its primary energy source by the mean of a Maximum Power Point Tracking (MPPT) to extract the potential maximum power which is nonlinearly depending on the weather conditions. In this work we presented...
This paper analyses the behaviour of the DC-link of a high power (50 kW), high frequency (150 kHz) voltage fed inverter with a series resonant load circuit for industrial induction heating applications which is characterized by a full bridge inverter with a power control based on pulse density modulation (PDM). The operation of this power control strategy can cause large oscillations of the voltage...
